Is surgery under general anesthesia dangerous? How much strain will chemotherapy put on my body? Won't healthy areas of the body also be affected by radiation? One thing is clear: cancer is our enemy and must be fought. However, the “weapons” that doctors need to do this are often very aggressive and weaken the body. But there is a therapy that can remove tumors and metastases gently, precisely and often even in just one session: CyberKnife therapy. A high-precision radiosurgery robot targets the tumor precisely, sparing the surrounding tissue. The world's most modern robot of this type is located at the European Radiosurgery Center Munich. Over 7000 patients have already been successfully treated here in around 15 years. Yet hardly anyone is familiar with this type of cancer therapy! Radiosurgeon and neurosurgeon Prof. Dr. med. Alexander Muacevic explains the most important questions about CyberKnife.
